' Appli n A ril 8. 194s,- serial No. 482,283 i 2 Claims. (01. 5745)invention relates to an improved apparahas for twisting of yarn and appg a treating solutionsuch as water, which may have admixed therewith apenetrating agent, if desired, and twisting the yarn while wet andsubjecting the yarn to a rubbing action to smooth the fuzz andoutstanding fibers thereon and to present a finished yarn whlclrto allintent purposes will have the appearance of singed yarn.

It is an object ofthis invention to provide an apparatus fortwistingyarn in which the yarn is brought from the conventional weightedfeed- Figure f. is a cross-sectional through the rubbing board, andshowing a modified form of ing rolls and is passed over a moisteningroll which applies moisture thereto, and then bringing the yarn over asurface where the yarn will not only be rubbed, but will be partiallytwisted on this surface, and this twisting or rotation of the yarn whilepassing over this surface will move the fibers and cause them to becomeembedded 1 in the yarn as it is being twisted.

It is a wellknown fact that cotton yarns have certain naturaLpilstherein which when moistened, permit the fibers of the yarn to sticktogether and cause the outstanding fibers from the yarn when pressed inthe yarn to adhere to the -body of the yarn,'and thus will remain inthis position when twisted, or otherwise treated after i this smoothingoperation.

It is another object of this invention to pro- I vide a method andapparatus for. twisting yarn the board without the groove therein.

Referring more specifically to the drawing, the numerals l0 and IIindicate a pair of bobbins in a twisting frame from which the yarn ispassed through an eye member l2 and over roll- Y er-s l3 and I4, andresting ori'top of the yarn as it roil it. The rolls i3 and I! aredriven by any suitable means such as a pinion It mounted. on shaft ll,which'shaft is driven by any suitable means. The rollers l3 and it aredriven by means of pinion i6 meshing with pinions i8 and l9 fixedlysecured on the ends of rollers ligand H. The structure thus fardescribed is conven-' tional structure, and it is with this conventionalstructure that I have associated my invention.

Instead of the conventional thread board on the twister frame, I providea stand 20, which has a trough 2| supported thereby, in which moisteningliquid 22a is placed. The trough is shown in section, and has the endnearest the observer removed therefrom. Mounted for rotation in thistrough is a suitable moisture applying roll 22, which is driven by anysuitable and applying a moistening agent to the yarn prior-to twisting,and then passingthe yarn on its way to the bobbin over a smoothingsurface which will smooth the outstanding fibers in the yarn bothlongitudinally and transversely of the yarn for the reason that therubbing action of the board or other member over which the yarn ispassed will smooth the fibers and the twisting action imparted to theyarn by the rotation of the bobbin will turn the yarn, or rotate theyamon the smoothing board, thus will cause the present a very smoothappearance to the yarn after itis twisted. t

i Some oi the objects of theinvention havin 7 been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawing, in which:

Figure 1 is an elevation, partly in section and partly shown inschematic form, showing my invention applied to a conventional twisterframe;

Figure 2 is an enlarged elevation of the upper Figure 3 is across-sectional view taken along the line-HinFigurel;

means such as by providing the pinion it with a friction face 23 andmounting a shaft 24 in an upstanding lug 25 of the stand 20 andproviding on the shaft 24 a key way 26, and on this shaft and key way, afriction wheel 21'is adjustably secured by any suitable means such as aset screw 28. The righthand end of shaft 24, as.viewed in Figures 1 and2, has a beveled gear 30 thereon which is adapted to mesh with anotherbeveled gear ii on the end of the shaft supporting the nbers to bepressed into the yarn to thereby roller 22. The roller 22, of course, issupported at itsend in suitable bearings not shown. By

adjusting the position of the friction wheel 21 along the shaft 24, therate of rotation imparted to moisture applying roll 22 can be adjustedas desired. I

The trough 2| is adapted to have therein any suitable treating liquidsuch as water, which may or may not be supplied with a penetrating agentto cause the moisture to be more rapidly applied to the yarn. Aplurality of yarn ends 35 and 36 which are led from the'bobbins l0 andii are shown as being two innumber in the drawing, but any desirednumber can be twisted together as desired. The yarn is passed through aneye l2 and above the rollers l3 and i4 and beneath the weighted rolleri5 which is pressing-onto the surfaces. of rollers" 13 and It, then itpasses over the moistening roll 22, and is then led over a passes overrollers t3 and, id is a weighted;

pressing or ironing board 40. This pressing or ironing board may have,if desired, a suit-' donning, so that it will not be in the way of thebobbin in dofling and donning th same. The board 46 has a pair of lugs42 and 43 which are pivotally secured as at 44 and 45 to links 46 and41, which links, in turn, are pivotally secured to lugs 48 and '49extending from stand by any suitable means such as pivots 50 and 5]. Thestand or support 20 is provided with a projection for each board or acontinuous projection indicated by reference character 52, which limitsthe downward travel of the board 40 and associated parts. At the lowerend of the board 40, there is provided a pig tall or eye member 55through which yarn passes to a traveller 56 on a ring 5'! disposed inconventional ring rail 58, and after passing beneath the traveller, itis wound around a bobbin 59 removably mounted on a spindle or bolster'60 which is driven by any suitable conventional means such as aconventional whorl 6| which has a belt therearound which also passesaround and is driven by the conventional cylinder of the twister whichis not shown.

As the plurality of strands of yarn are led through the apparatus to thebobbin 59, they are, of course, moistened by contact with the roller isregulated, to apply a small additiona1 amount of moisture to the yarn,and since the roving does.

not have to pass through any drawing rolls after moisture is appliedthereto, the roving can be spun by the apparatus shown, though it mightbe desirable to have a regular spinning ring and spinning travellerinstead of the twister ring and twister traveller shown in the drawing.By regulating the speed at which the moisture applying roll is driven,it can be made to turn very slowly, if desired, to apply the desiredamount of moisture to the roving.

All modern spinning and twisting mills at the present time are equippedwith humidification apparatus, the purpose being to apply a certainamount of moisture to the yarn by the medium of the atmosphere of themill, and by applying a small additional amount of moisture to the rowings, better spinning action can be obtained.

By the time the yarn, after it is spun, is ready to be twisted or plied,it has usually lost a good amount of its moisture, and in a twistingoperation, the speed of the moisture applying roll would be increased toapply whatever amount of moisture would give the best results intwisting.

This apparatus can not only be used for applying moisture, but also anysuitable agent such as mildew proofing, fire proofing, dyeing, waxing,glazing, waterproofing, oil treating, resin treating, softening, or anyother desired treating agent.

By the use of this apparatus, it is evident that by applying moistureduring spinning or twist- 22 which lifts moisture fromthe trough 2|. As

the yarns travel downwardly on the board 40, they are, of course,twisted by the action of the twisting operation on account of therotation of the bobbin 59 which twists the yarn as it appears betweenthe eye 55 and the traveller 56. This twisting will also extend upwardlyin the trough 4|. The twisting operation while the yarn is in contactwith the board will rub the yarn by rotatin the same on the board, andwill thus embed the fibers radially into the yarn or rather spirallyinto the yarn as the yarn will be travelling down the board while it isbeing rotated, and thus the fibers will be' impressed into the surfaceof the yarn, and the smoothing action or double ironing action will takeplace both by the longitudinal travel of the yarn and by the rotativeaction imparted thereto by the twisting operation. After the yarn isthus smoothed and twisted, it is deposited onto the twister bobbin 59and in this smooth and twisted condition, and a moist condition as well,the fibers will be set in this condition and the result will be a verysmooth yarn which will not have to be singed, as a general rule, andfurthermore, the yarn will be treated with the moistening agent and thuswill eliminate the necessity of package treating of the yarn, which isnow carried out on yarn twisted in the conventional manner.

By applying the moisture to the yarn as it is twisted, the yarn will betwisted in this moist con: dition, and will be ready for workingoperation without the necessity of placing the packages of yarn in amoistening machine or conditioning machine, ano passing the sametherethrough prior to a working operation.

This apparatus is adaptable for spinning, as well as twisting. It isrealized that though wet roving probably could not be spunsatisfactorily, but if the amount of moisture applied to a roving ing,the fluid will soften the natural gumsin the fibers, and they willbemore firmlyset and embedded in the surface of the strands, and eventhe interior fibers will be bound together, so that a greater breakingstrength is imparted to the yarn than would be otherwise the case.

In the drawing and specification, there has been set forth a preferredembodiment of the invention, and although specific terms are employed,they are used in a generic and descriptive sense only and not forpurposes of limitation,

. the scope of the invention being defined in the claims.
